If (m+n)^2=m^2+n^2, what is (3^m)^n?

svp [43]

Answer:

$(3^m)^n=1$

Step-by-step explanation:

$(m+n)^2=m^2+n^2\\m^2+2mn+n^2=m^2+n^2\\(m^2+n^2)-(m^2+n^2)+2mn=0\\2mn=0\\This\ equation\ has\ two\ solutions\ : m=0,n=0\\\\But\ either\ way\ will\ result\ in\ the\ same\ answer.\\If\ m=0\ then,\\(3^0)^n\\=1^n\\=1\\\\If\ n=0 \ then,\\(3^m)^0\\=1$

Please help me with this problem......

kupik [55]

The red graph is the result of a vertical translation, 4 units down, of the black graph.

This means that, whenever the black graph associates

$x\mapsto f(x)$

The red graph must associate 4 less to the same input:

$x\mapsto f(x)-4$

So, the equation for the red graph is

$y=f(x)-4$

or, equivalently,

$y+4=f(x)$
